How to handle multiple client with one project ?

Question

Hello,

 

I am developing one project in Asp.net MVC and SQL server 2014.

 

Now the question is how to handle multiple clients with a single application with a single DB? 

 

should I create a Separate DB instance and Application instance?

 

OR

 

Should I use a single DB and an Application for multiple client? 

 

Please give me a suggestion for the future scope of the project.
